A, "Application filed March 313932;; seriai nofioaezs; i 1' I inventionrelates tofimprovementsiin drain fittings of the type wherein the drainclosing. mechanism is' operated bymeans of a liftrod extendingthrou'gh'and backjof the fixture upon which the drain fitting inestalledi' I f T Such fittings'have achieved a high degree of popularity,as theypossess numerous advantages ,overjother typesof drain fittings. Il

However, since friction betweentherparts;

is relied uponlto'maintain the drain fitting in its lifted or drainingposition, when the parts becomesomewhat worn and the friction betweenthem is lessened, the drain is apt .to

" close by itself, preventing complete draining It is anobject ofniyinvention to obviate: rod this difiiculty by providing :means to createsufficient friction to vassure that-,the valve will remain open untilclosed by the operator.

Further objects will beapparent; from the following description.
